Quality Meat Scotland will use the Edinburgh Gunners man as the focal point for a television and poster campaign for a range of Scotch Beef adverts.
The advert was filmed at Murrayfield and will emphasise the link between sport and a healthy balanced diet.
SRU marketing director Phil Anderton, said: "We are delighted to add another partner to Scottish Rugby's sponsorship portfolio.
"Scottish rugby is currently undergoing an exciting period of change. This new partnership with a company with similar quality values to Scottish Rugby provides us with an opportunity to draw on QMS's links with the retail sector and gain exposure for Scottish rugby to an ever widening audience."
